MACHINE FOR WTTING PAPER.V

Specification forming part of Letters Patent No. 28,895. dated June 2G,1860.

To a/ZZ whom it may concern.-

Beit known that I, ANDREW OvEREND, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a new and usefulMachine for Vettiug Paper Preparatory to the Printing thereof; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, in which- Figure l is a sideelevation of my invention; Fig. 2,a side sectional view of the same;Fig. 3, a sectional plan or top view of the same; Fig. ga horizontalsection of the same, taken in the line Fig. l.

Similar letters of referenceindicate corresponding parts in the severalfigures.

The object of this invention is to obtain a machine by which paper maybe moistened in a very expeditious and thorough manner preparatory tothe printing thereof.

The invention consists, substantially, in the employment or use of areciprocating frame, perforated water-supply tubes, feed and receivingboards or platforms, and a holding device arranged for joint operation,as hereinafter described, to effect t-he desired end.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A representsa framing, which may be constructed in any proper way tosupport the working parts, and B B are two parallel ways securedhorizontally in the framing A at its upper part. On these ways a frameor carriage Gis placed, said carriage being provided at each side withrollers l) l), which run on the ways B B. The carriage C is formed of arectangular frame having wires fitted longitudinally in it at a suitabledistance apart, as

shown clearly in Fig. 3.

In the lower part of the framing there is placed horizontally adriving-shaft D,on one end of which a wheel E is secured. This wheel Ehas a heartshaped recess or groove c at its inner' side, in whichrecess. or groove a pin d at `the upper end of an arm F is fitted. Thelower end of the'arm F is attached to a shaft Gin the lower part of theframing, said shaft being provided with an arm H, which extends upwardand passes through an eye e at the outer part of the carriage C.

I I J J are four tubes, which are placed in the framing A, two above andtwo below the waysB B of the carriage C, as shown in Figs. l and 2.These tubes I I J J communicate with a water-reservoir or with pumps,and the under sides of the upper tubes I I are perforated, and also theupper sides of the lower tubes J J, as shown at e in Fig. 2.

At one end of the driving-shaft D adjoining the wheel E there' is placedan eccentric K, which bears against the lower end of an" arm or lever L,attached to one side of the framing. The lever L has connected to it apawl M, which engages with a ratchet N at one end of a shaft O, which isdirectly above the shaft D and in the same axial plane.

At about the center of the shaft O there is a pinion P, which gears intoa vertical rack Q, attached to one end of a platform R. This platform Ris iitted between guides ff in the framing, as shown in Fig. Ll. To eachside of the platform R a vertical rod or bar S is attached, the upperends of which form bearings for a shaft T, on which a roller U isplaced. The bars S pass through suitable guides g, attached totheframing. (See Fig. l.)

On the upper part of the framing' A there is placed a platform V, whichis directly over the platform R and nearly or quite equal in length toit. (See Figs. l and 2.)

To the inner side of the wheel E there is secured a curved arm X, theform of which is shown clearly in Figs. l. and 2, mostly by dottedlines. Against the outer side 'of this curved arm X the upper end of anarm Y bears, said arm being attached to one end of a shaft Z, which isin the lower part of the framing A and has a spiral spring A on it, saidspring keeping the arm Y in contact with the curved arm X or with-a stopattached to the framing A.

To the shaft Z two curved arms B B are attached. These arms'B B extendupward above the platform R nearly to the ways B B, and their upper endsare connected by a plate C. To the ends of the ways B B and over t-heplate C there is placed a rod D', the ends h of which are bent at rightangles with its main portion and are fitted in loops or eyes z',attached to the ways B B. One of the ends 7L of the rods D' is bentinward a short distancetoward the center of the framing, as

shown by the dotted lines in Fig. 3, and to the front end of thecarriage C at one side there is a swinging pendantj.

Through the platform R four rods 7c pass, each rod having a spiralspringl placed on it. The rods 7c are fitted loosely on the platform andthe lower ends of the springs Z rest on the platform. To the upper endsof the rods k a plate E is attached. This plate E is parallel With theplatform R and rests on the springs Z, the rods 7a serving' as guides.

The operation is as follows: The paper to be moistened (shown in blue)is placed on the platform V and is folded in quires or in bundles of anysuitable number of sheets. The roller U rests on the top of the pile ofsheets on the platform V and the wheel E is rotated by any convenientpower. As the wheel E rotates, a reciprocating movement is given thecarriage C by means of the groove c, arm F, shaft G, and arm II, andeach time the carriage C reaches the termination of its stroke whenmoving in the direction of arrow l the attendant places a bundle ofpaperon the carriage C,

and the carriage in moving in the direction indicated by arrow 2 passesbetween the perforated tubes I I J J, and the paper on the carriage haswater ejected against its upper and lower surfaces, the water beingejected through the perforations e of the tubes. As the carriage Capproaches the termination of its stroke in the direction indicated byarrow 2, the pendantj strikes one of the arms 7L of the rod D andelevates said rod, so that the edge of the quire or bundle of paper onthe carriage C will pass under said rod. As the carriage C recedes ormoves in the direction of arrow l, the rod D drops on the paper, holdinit on plate C', and the carriage C moves from underneath the paper,which, When the carriage is fully from underneath it, is allowed to dropon the plate E by the removal of the plate C outward from underneath therod D', thc plate C being actuated or thrown outward from the rod D atthe proper time through the medium of the arms I3 Y X, the spring A atthe' proper time throwing back the plate C toward the rod D', so thatthe rod D may hold the succeeding bundle or quire of paper at the returnof the carriage C. Each time the carriage C reaches the termination ofits movement in the direction of arrow l the eccentric K actuates thearm L, and the latter moves the pawl M, which actuates the ratchet Nsufficiently for the pinion P to slightlyv elevate the rack Q, andconsequentlythe platforms R V. rIhis elevation of the platforms occursjust at the time the operator removes a. quire or bundle of paper fromthe platform V, and the movement is essential in order that the paper onV be relieved for an instant of the pressure of the roller U to enablethe operator to remove the top quire or bundle from V. As the paper isfed off from the platform V, is moistened, and dropped on the plate E',the latter, with platform R, descends as the roller U rests or bears onthe top quire orbundle on V. Consequently the paper on E will not beallowed to come in contact with the lower tubes J J.

The machine, it will be seen, works automatically, one operation beingrequired only to feed the paper to the carriage C and remove from timeto time the moistened paper from the plate E. The water maybe ejectedthrough the tubes I J either by hydrostatic pressure or by pumps.

IIaving thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The reciprocating carriage C, combined with the perforated water-tubes II J J, the feed and receiving platforms V R t', and the paper holdingand discharging device formed of the rod D and plate C', or theirequivalents, arranged for joint operation, substantially as described.
